Given that it was one of the pre-existing tests that failed I'm happy that we are covering this issue. All of these LRA related issues are likely to phase in and out with subtle changes to code-gen so I don't think we can always get a test case that fails on trunk. Since Catherine asked for further info then I will leave her to say if she is happy to accept on this basis. Matthew
